The 13 should be 31... then
1+1+1=3
1+1+3=5
1+3+5=9...
The next number in the sequence is 27.
17?
These are all prime numbers. The next one is 17
33
17
The pattern consists of consecutive prime numbers: 2, 3, 5, 7, 11, and 13. The next prime number after 13 is 17. Therefore, the next number in the pattern is 17.
13
If you eliminate the first number, the rest are prime and the next one would be 29.
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
The pattern alternates between adding 11 and adding 2. Starting with 11, we add 11 to get 22, then add 2 to get 13, and continue this pattern. Following this sequence, after 17, we add 11, resulting in 28. Therefore, the next number is 28.
The next number in the sequence is 27.
8
The pattern appears to be: subtract 6, add 17, subtract 14, add 9, subtract 7. Following this pattern, the next number should be obtained by adding 3 to the last number in the sequence, which is 6. Therefore, the next number in the sequence is 9.
17
-13
To find the next number in the series, we can observe the alternating pattern between pairs of numbers. The first number is 14, and it decreases by 3 to 11, then increases by 7 to 18. Following this pattern, the next number after 18 should decrease by 2, resulting in 16. Therefore, the next number in the series is 16.
The rule for the pattern 9, 13, 17, 21, 25 is that each number increases by 4 from the previous number. This can be expressed mathematically as: each term can be represented by the formula ( a_n = 9 + 4(n - 1) ), where ( n ) is the position of the term in the sequence. Thus, the pattern continues by adding 4 to the last number to generate the next one.
